This week, a Virginia judge ordered a Yelp user to change a negative review. Before we get into the specifics, just think about that for a second. Do you use Yelp (or any other service for that matter) to discuss your experiences at restaurants or with other businesses? Have you ever left a negative review of a business? Depending on what you say and how the business in question reacts, that freedom of speech thing you've grown so fond of may not be enough to hold up in a court of law.
